My little is 3 weeks old, had regained her birth weight back just before 3 weeks old. The lactation consultant has me topping her up with either formula or expressed breast milk every second feeding and taking supplements to increase my supply. I pump after every second feeding (alternate feedings with the top up and pump) she has more than enough wet diapers but doesn’t poop well (my first had this same issue), she can sleep and eat in stretches up to 4 hours at night or as little as 45 minutes between feeds, when I pump I get anywhere from just under 1oz to almost 2oz (both breasts combined)

What’s considered normal? Is my baby actually getting enough? Should I keep breast feeding? It just feels overwhelming and I feel like I’m not giving her enough. How did you increase your supply? Ant advice is appreciated
